This article examines Excited Delirium, a controversial medical explanation offered as an explanation for a variety of in-custody deaths. It appears to fit all essential criteria to incite a moral panic, featuring a powerful moral entrepreneur playing off of well-established fears of drugs use and psychosis, with a classic folk devil in the form of young men of color. Yet Excited Delirium has failed to provoke a widespread response, raising the question of how a phenomenon that meets all the classic criteria can fail to incite a moral panic. I argue this stems from the entrepreneurs involved failing to present themselves as sufficiently moral, their campaign to medicalize the phenomenon meeting an unreceptive medical field, and their broad conception of Excited Delirium too easily facilitating strong counter-narratives. This study uses Excited Delirium as a negative case to demonstrate several important factors to consider in the development of moral panics.
